User manual

Crop preserves the aspect ratio and scales the image to fit the screen. Dependant on the aspect ratio of
the panel either the top and bottom or right and left areas of the image are cropped.
Anamorphic scales the input image such that it is displayed with a 16:9 aspect ratio when displayed on
the screen. The image is further scaled to fit into the size of the panel. Dependant on the aspect ratio of
the panel the image is then either bordered by the right and left side or bottom and top of the panel.
Non-used areas of the panel are displayed black (letterboxed).
3.7.5. Aspect Ratio
Settings: Scale, Preserve
The system can be set to scale the input image to a fixed output resolution or, with the setting preserve,
to chose an output resolution matching the input resolution. If no matching output resolution is available
or no input is detected, the pre-defined output resolution is used.
3.7.6. Overscan
Settings: 0 to 10 in steps of 1
Overscan is used to slightly zoom into the image when the border area of an image is no longer
displayed on the screen. This cuts off unwanted features at the top or bottom.
3.7.7. Pan Tilt Zoom
This menu provides settings to zoom and shrink the image, as well as panning within the image.
Pan Tilt Zoom (PTZ) can be switched ON or OFF.
Note :- When switching on the latency of the system is increased by one frame. Thus, there is a
difference of a PTZ setting OFF or ON with no zoom.
Note :- PTZ settings can be saved per mode or globally, if set to global the same PTZ settings are
applied when switching input channels or if set to per mode the PTZ setting will only be applied to the
input you have selected.
The Zoom slider allows to zoom into the image or shrink it.
When Aspect Lock is set to ON the separate slider for zooming vertically is greyed out and the
horizontal zoom or shrink factor is used as vertical factor as well. The aspect ratio is preserved.
When Aspect Lock is OFF horizontal and vertical scaling factors can be chosen separately.
With the Pan and Tilt sliders panning within the image in horizontal and vertical direction is possible. Off
raster panning is allowed, the image can be shifted outside the active area of the display.
For convenience the PTZ settings can be reset with one button.
